Hello,
I am trying to understand something about PicoLisp and Fixpoint numbers.

I am writing an app and would consider PicoLisp should I get my head
around Lisp. But I do not understand how to use numbers.

I use a lot of floating point numbers and lots of calculations. From
simple experiments it seems that the numbers and math appear to be
accurate and correct. However I have no understanding of how to present
a final result formatted correctly.

From another language 20 decimal points printed after converting to
floating point:

927.23474457900010747835

The math looks fine as far as these simple examples go. But if I do
several to dozens of different calculations with floating point numbers
with unknown values until streamed to the app from some source. How do I
know where the decimal point really belongs in order to format correctly
for human use? Is it possible?

I personally do not have a problem with fixpoint for internal use, as
that is simply an implementation issue. However I do need to convert
back to the best floating point representation for display or storage.
